D is your answer
Have a good day :)
x^2*(-3x)=-3x^3. The power of x becomes 3 because you add the powers of x. (2+1=3)
Answer:
they are equal
Step-by-step explanation:
because you can add how many zeroes after 2.79 but it is going to still be equal.
H = 4(x + 3y) + 2
H = 4x + 12y + 2
H - 12y - 2 = 4x
(H - 12y - 2) / 4 = x or 1/4H - 3y - 1/2 = x
